Jobs revealed in an email to employees today that his health issues are more complex than he originally thought (he previously said he was suffering from a hormonal imbalance). In the meantime, Apple's chief operating officer, Tim Cook, will take over Jobs' day-to-day duties while he is on leave, although Jobs still plans to maintain his CEO role by being a part of major strategic decisions.

A sad Apple news day indeed. We hope that Steve takes this time to focus on his health so that he can come back, full-steam ahead, this Summer.
